Good morning,
I'm studying the "state of the art" of accessible anti-robot
form validations.
What I have by now is:
- an audio alternative for the image generated on the fly, but this
cannot be used as the only alternative
- a calculation question like "Enter the total for 23 + 4", what
apparently can be solved by some robots
- two "human" questions to be answered, that must be changed frequently
I'd appreciate to have your feed-back on this (problems,
constraints, etc.) and to have some new ideas.
Thanks a lot!
